A convertible vehicle door assembly includes a gate subassembly including an electrical panel, latch handle and is secured by hinges and a latch to a vehicle static structure. An outer door subassembly is removably secured to the gate subassembly by at least one quick connect mechanism. The outer door includes a window assembly operable by the electrical control panel.

A vehicle includes a door with an interior door cavity, as well as a lock rod and another item of a locking system, an impact beam, an attack member and a push member, all housed in the interior door cavity. The impact beam crosses the other item from laterally between the other item and the door. The attack member faces the lock rod from laterally between the door and the lock rod. The push member, along the impact beam, faces the other item from laterally between the other item and the door and laterally beyond the impact beam. When the door collapses when compromised by a side impact event, the door carries the attack member for attacking action on the lock rod. The door additionally carries the push member for counterpart pushing action on the other item. A connection between the lock rod and the other item thus breaks.

A vehicle includes a body that defines a front door opening, and includes an A-pillar framing the front door opening, and a door over the front door opening. The front door includes an inner door panel and an outer door panel defining an interior door cavity therebetween. The vehicle also includes an impact beam and a transfer member housed in the interior door cavity. The impact beam has a forward end that laterally overlaps the A-pillar. The transfer member laterally overlaps the A-pillar in common with the forward end of the impact beam, and faces the inner door panel from laterally between the forward end of the impact beam and the inner door panel. When the vehicle experiences a side impact event, the A-pillar assumes side impact energy via transfer from the forward end of the impact beam through the transfer member.

A convertible vehicle door assembly is disclosed and includes a gate subassembly including an electrical panel, latch handle and is secured by hinges and a latch to a vehicle static structure. An outer door subassembly is removably secured to the gate subassembly by at least one quick connect mechanism. The outer door includes a window assembly operable by the electrical control panel.

A vehicle side portion structure includes a vehicle body side portion in which a door opening portion allowing an occupant to enter or leave a vehicle is formed, the vehicle body side portion being configured to include a center pillar dividing the door opening portion into front and rear portions, a slide door disposed such that the door opening portion is openable and closable, the slide door in a closed state being disposed across the center pillar in a front-rear direction of the vehicle, and an elongated reinforcing member disposed inside the slide door with a longitudinal direction of the reinforcing member directed in the front-rear direction of the vehicle and intersecting with the center pillar in side view of the vehicle in the state where the slide door is closed.

A vehicle door assembly includes a door housing configured for covering a vehicle access opening. An intrusion beam is within the door housing. A module is received on the intrusion beam and removable from the door housing. A module hinge assembly is attachable to the module. A module latch assembly is attachable to the module for securing the module to extend across the vehicle access opening. A modular vehicle door assembly and method are also disclosed.

A vehicle door assembly includes a door housing configured for covering a vehicle access opening. A frame member is disposed within the door housing. A module includes an intrusion beam coupled to the frame member and removable from the door housing. The module is configured to accept attachment of a module hinge and a module latch to provide a secondary door assembly. A modular vehicle door assembly and a method of assembling a door assembly to a vehicle are also disclosed.

Guide rails with which a window regulator is provided are respectively fixed to a module plate. The guide rails are fixed, together with the module plate, to an edge of an opening portion provided at inward frames from an outward side in a vehicle width direction. Attachment portions which are capable of afterward attaching outward frames to the inward frames are provided, and attachment portions which are capable of afterward attaching a door outer panel to a door frame comprising the inward frames and the outward frames are provided.

A method includes molding an outer impact beam made of carbon fiber reinforced plastics (CFRP) and separately molding an inner impact beam made of CFRP. The outer impact beam and the inner impact beam are coupled to each other to form an impact beam and the impact beam is coupled to an inner panel of a vehicle door.
